IUH-F190-V1-*, IUT-F190-R4-V1*
Operation
Q Value QW
In accordance with EPC Gen 2 (ISO/IEC 18000-63), the slotted ALOHA principle is used for
anticollision. The number of time slots is defined as 2
value. As a guide, the number of time slots should roughly correspond to the number of
expected tags in the measurement range.
ParamTyp:
Default:
Value range:
Example:
WP1UQW.00.01.04 sets the Q value to 4. The read/write head therefore works with 2
time slots.
RP1UQW.00.00 outputs the set Q value.
Country Identifier, "Region Code"
The RC parameter reads out the country identifier.
ParamTyp:
Value range:
Example:
RP1URC.00.00 reads out the set country identifier.
The country identifier consists of 2 bytes. The first byte always has the value 80. The second
byte corresponds to the country identifier. The serial response .30.31.80.01 indicates the
country identifier for Europe.
